Dark spots on my paper

When we print we get dark spotts on the paper that look like tire tracks down the entire right side of the paper. the dark spot is about 1 1/2 inches wide. Do you have any suggestions on what is wrong? We have tried to clean this ourself by cleaning anything in site that was dirty. No Luck. We even had our computer guy look at it and he had no luck.

Re: dark spots on my paper

You should clean the developer unit, it's placed behind the toner cassette. Pull the toner cassette out first, than pull the developer unit out and clean toner spots on it's roller.

Re: dark spots on my paper

Is there a corona wire sliding cleaner on the drum assy? if so it should be firmly at the correct end of its travel - on some printers if it is inboard it will print aline down the side

It's probably the transfer roller. Generally straight lines or repeated spots come from a dirty or damaged transfer roller.

I am using Premium Kodak Photo Paper and selecting photo paper in the preferences which I have used successfully before, but have just started having trouble. It started by printing a dark band more than...

Hello. By the sound of it the paper is slowing down at the point were the dark band is. If you can pay close attention to the speed of the paper the entire print. If is appears to slow down, then feeds out correctly, there are two things to look for. The Paper could be sticking in the tray at that point or the rollers are loosing grip. It can also be a combination of both. Make sure no ink or dust has built up in the rollers and also make sure you dont overload the paper feed tray. This increases the bend of the paper through the rollers and can cause them to slip.
Other than this the rollers can be re-set or replaced but it is normally not economical to do so.
I hope this helps Regards GM

Sharp AL-1631 bottom paper feed will not pick up paper.

A few things could be the problem.
  1. The paper in tray could be damaged
  2. The drawer separator pawls (metal taps on the right side of tray where paper touches)
  3. Paper backstop not in or in wrong spot (green plastic piece at back of paper)
  4. Feed tires are worn or dirty
Does the copier try and feed from tray 2? If it tries but the paper doesn't leave the try look and see if there is a dark mark on the page (top middle towards the right). If so then most likely the feed tire is worn.

Dark spots on the left side of the paper

To solve the printing problem..

# Hold the cartridge upside down, with the bar-code label facing you and take a damp paper towel.
# Use the towel to wipe the printhead of the cartridge on the bottom (where the ink comes out). Wipe the printhead horizontally in one direction only (left to right).
# Continue doing this until it looks clean.
# Then dab the cartridge on the towel to make sure the ink is flowing.
# Next, look inside the printer and locate the carrier that holds ink cartridges. Caution: Make sure the cartridges are not installed at this point.

1. Look for a shiny piece of metal underneath the contacts at the back of the carrier.
2. Take a damp cotton swab (use water only!) and wipe along the bottom of the shiny metal piece. Note: You may need more than one swab.

# Reinstall the cartridges, making sure you snap them correctly into the printer.

It most likely needs a new feed tire and seperation pad. You can buy at

For now do this, take a clean rag and dampen it with water or alchohol. Remove your paper tray, carefully hold it in the front middle under the pick up tire while also holding up the small black paper sensor. When you see a green light, press doen the top button 2 secs then down two more times. It should then try to print and this will cycle the print tire and you will be able to wipe the entire tire with your rag. Good Luck!

Ink cartridges come off carriage

I'm not too familiar with the 12xx family of printers, but sounds to me like you have broken the print head track arm. Look carefully at the side that has come off the track. The traditional Epson print head design is to have the top track arm as part of the print head, and the bottom track arm as part of the print head carrier. The print head and carrier clip together thus providing a closed arm over the track rail. The key question is, have you merely unclipped the print head and carrier? If so all you need to do is position the upper and lower jaws over the track and push the print head and carrier parts together until they click. Alternatively, is a lower or upper jaw missing? In which case, one or other is broken - disaster I'm afraid.

Remember, I'm talking about generic Epson design of the 1290 vintage. I have the 1290 service manual, which is of the usual Epson rubbishy standard, but it's not the same as having actually dismantled one, which I haven't. However, if you look carefully at the side of the print head that's come off the track rail, you should be able to spot if anything is missing i.e. broken off.

First, on your computer desktop. left click on START. Next, left click on CONTROL PANEL, and left click on PRINTERS. Find your printer on the PRINTERS window, and RIGHT CLICK on the icon. From the drop-down menu, left click on PRINTING PREFERENCES. Use the settings to set up the printer for the paper size and orientation you want to use.Click APPLY , then OK buttons to apply any changes you make. If that does not help,check the side paper guides in the paper source you are using. If they are not against the paper on both sides, the paper will not align properly with the image. Move the guides snug but not tight against the paper. If the guides are too tight, paper may not feed. If moving the guides does not solve the problem, try loosening the guides and reposition the paper until the image is properly aligned. Then see in your owners manual if there is an adjustment called SIDE-TO-SIDE REGISTRATION, and follow the proceedure to adjust the side-to side paper alignment.
